本文介绍了具有升压功能的矩阵转换器。该电路拓扑在矩阵变换器的输入侧连接一个V型交流斩波器，实现升压功能。矩阵变换器和V连接AC斩波器被独立地控制，其中虚拟间接控制方法被应用于矩阵变换器，并且开环控制被应用于V连接AC斩波器。然而，由于V型连接交流斩波器的额外损耗，所提出的电路的效率较低。在本文中，所提出的电路和传统的矩阵变换器的效率进行了评估，通过使用一个3.7kW的IPM电机在仿真和实验。仿真结果表明，采用弱磁控制后，传统矩阵变换器的损耗比所提出的电路拓扑低，效率提高了12%。根据实验结果，它是获得所提出的电路可以提高效率的13%，与传统的矩阵变换器相比。
This paper describes the matrix converter that features boost-up functionality. The proposed circuit topology connects a V-connection AC chopper at the input side of the matrix converter to achieve the boost-up function. The matrix converter and the V-connection AC chopper are controlled independently, where a virtual indirect control method is applied to the matrix converter, and an open-loop control is applied to the V-connection AC chopper. However, the efficiency of the proposed circuit is low due to the extra loss from the V-connection AC chopper. In this paper, the efficiency of the proposed circuit and the conventional matrix converter is evaluated by using a 3.7kW IPM motor in the simulation and the experiment. The simulation results confirm that by implementing field-weakening control in the conventional matrix converter, the losses are lower than that of the proposed circuit topology, where the proposed circuit improves the efficiency by 12%. According to the experimental results, it is obtained that the proposed circuit can improve the efficiency of 13% in compare with the conventional matrix converter.
